Reassessment under Sections 147 and 148 is sustainable where Investigation Wing information on substantial bank cash deposits constitutes tangible material and the Assessing Officer forms a belief that income escaped assessment, rather than acting on mere suspicion or a change of opinion. Cash deposits recorded as cash sales may be added as unexplained cash credits when the taxpayer cannot establish a nexus between the alleged sales, stock movement and bank deposits. Invoices and cash-book entries alone do not prove the genuineness of substantial cash receipts. On these facts, both the reopening and the unexplained cash-credit addition remain sustainable.

Pure reimbursement of common-area maintenance payments made at actual cost without mark-up does not attract tax deduction at source. Such payments merely recoup the underlying maintenance expenses and therefore cannot result in the payer being treated as an assessee in default for short deduction. No liability arises under Sections 201(1) and 201(1A).

Section 56(2)(x) does not apply where the substantive property transaction was completed before its 1 April 2017 effective date, notwithstanding later registration. Full consideration, execution of the binding sale deed, delivery of possession and initiation of stamp-duty adjudication before that date establish pre-effective completion. Registration later merely culminates the earlier transaction. The stamp-duty valuation also lacked finality, while the valuer's report placed the property value below the agreed consideration. The addition under Section 56(2)(x) was therefore deleted.

Sections 69A and 69B require evidence of unexplained money or investment exceeding recorded amounts. Cash returned by builders that is traceable to accounted bank-channel advances, without proof of an independent unexplained source, asset, income or accretion, should not be separately treated as unexplained money or investment. Alleged interest from purported builder financing similarly requires material beyond an inferred financing arrangement. For immovable property acquired below stamp duty value beyond the statutory threshold, section 56(2)(x)(b) may apply irrespective of transaction characterisation. Where stamp duty value is disputed, the section 50C valuation mechanism requires fair market value determination through the Departmental Valuation Officer before taxability and quantum are finalised.

Section 270A(6)(a) excludes disclosed expenditure from under-reported income where the taxpayer gives a bona fide explanation and fully discloses material facts. Software-development expenditure, including impairment of an internally developed software asset and capital work-in-progress, was disclosed in audited financial statements. The dispute concerned whether that expenditure was revenue or capital in nature, not fictitious claims, inflated expenditure, false statements, or suppressed facts. Rejection of an arguable legal claim in quantum proceedings did not negate the bona fide explanation. The amount was therefore excluded from under-reported income and the penalty was deleted.

Compulsorily convertible debentures retain their pre-conversion contractual coupon obligation despite a future conversion requirement, particularly where holders lack equity rights before conversion and the conversion price is determined later at fair market value. Under the arm's-length principle, a nil price for CCD interest requires comparable-based analysis under the prescribed transfer-pricing method; long tenure, mandatory conversion, or no cash redemption may justify comparability adjustments but do not alone permit recharacterisation. Recharacterisation requires evidence that legal form and economic substance diverge or that the arrangement cannot be reliably priced. Interest deductibility or capitalisation depends on fund utilisation and supporting records, not merely on characterising unconverted CCDs as equity.

Under the project-completion method, income from sale of flats, including survey-disclosed on-money, accrues when sale deeds are executed and title transfers, not when advance consideration is received. On-money consistently offered in the respective registration years, including amounts covered by undertakings for subsequent years, receives corresponding treatment. Sustained additions require limited verification: amounts taxed in the relevant subsequent years must be deleted, while unoffered amounts may be assessed in the year under review, with no deferral beyond the undertaking period.

Related-party commission payments may be disallowed as excessive or unreasonable only where the payment exceeds the fair market value of services, the legitimate needs of the business, or the benefit derived. A payment to a specified related person does not itself justify disallowance. Commission benchmarks must be based on genuinely comparable businesses; comparison with an unrelated business model cannot establish excessiveness. Verification should address the actual services rendered and their commercial justification. Where no comparable material demonstrates that commission paid to a spouse's proprietary concern was excessive or unreasonable, disallowance of the expenditure is unsustainable.

Alleged bogus purchases may warrant a limited addition where banking payments and GST registration are unsupported by verifiable counterparties or contemporaneous records; only 3% of the disputed purchases remains added. Unexplained expenditure requires proof that the assessee actually incurred it and a nexus supported by invoices, payment trails, goods movement, or other independent evidence. Uncorroborated third-party statements and unilateral GST reporting do not establish such expenditure, so the accommodation-entry addition does not survive. Commission additions based only on presumption or estimation, without proof of payment or a financial trail, are also deleted.

Political-party donation deductions are unavailable when seized material and sworn statements establish an accommodation-entry arrangement, cash repayment after commission, and the taxpayer produces no rebuttal evidence. The statutory presumption concerning seized material and the evidentiary value of search statements support treating the contribution as non-genuine. Interest on borrowed capital claimed for house construction depends on proof of actual construction and loan use; a loan labelled personal may qualify only after verification of supporting evidence. Tax-credit and professional-tax adjustments must be given effect in accordance with law.

Reassessment jurisdiction under Sections 147 and 148 requires a reason to believe that taxable income escaped assessment based on correct and relevant facts available when jurisdiction is assumed. Where a registered sale deed already held by the Assessing Officer showed joint ownership, recorded reasons could not validly attribute the entire sale consideration to one owner. Acceptance of a lower ownership share during reassessment could not cure that initial factual defect. The notice and consequential reassessment proceedings were therefore void ab initio.

Unexplained expenditure and unexplained money additions require reliable evidence linking the alleged expenditure or funds to the assessee. Third-party entries alone are insufficient where the underlying seized material is not furnished, effective cross-examination is unavailable, and no independent corroboration-such as a cash trail, bank withdrawal, delivery record, stock discrepancy, or confirmation-establishes incurrence, possession, or ownership. Presumptive income disclosure does not by itself validate an alleged unrecorded purchase. On this evidentiary approach, additions under sections 69C and 69A, together with consequential tax and penalty consequences, lack a sustainable foundation.

Reassessment initiated beyond four years requires a reasoned belief that income escaped assessment because the taxpayer failed to make a full and true disclosure of material facts. Third-party search information adopted without independent enquiry or a direct nexus to the taxpayer's records does not meet that jurisdictional threshold; the reassessment was therefore quashed. Section 69C requires proof that unexplained expenditure was actually incurred. Where export receipts were supported by contemporaneous business, customs and banking records, uncorroborated third-party material without effective cross-examination could not establish cash payments or unexplained expenditure. The addition was deleted, avoiding double taxation of recorded export receipts.

Appellate review must decide on the merits a disallowance arising from an assessment order; the existence of a separate additional claim does not justify refusing to determine that challenge. The disallowance therefore requires fresh merits adjudication by the Tribunal. Conversely, a fresh bad-debt claim first raised before the first appellate authority cannot be entertained where it neither arises from the reassessment nor falls within the scope of the underlying revision proceedings. That additional claim is unavailable in those appellate proceedings.

Banking companies governed by the Banking Regulation Act, 1949 fall outside the minimum alternate tax regime under Section 115JB. Leave-encashment liability may accrue under the mercantile system, but Section 43B(f) defers its tax deduction until actual payment to the employee. UPS qualifies for depreciation at the computer-equipment rate where it forms an integral part of the computer system and lacks independent functional use. Accordingly, minimum alternate tax does not apply to the banking company, leave-salary provision is deductible only on payment, and UPS receives computer-equipment depreciation.

Final assessment is unsustainable where a timely uploaded adjournment request is not considered because of a system-related inwarding delay. Natural justice requires a meaningful opportunity for the assessee to respond before finalisation. Portal records showing that the request was filed within the compliance period, but was not placed before the Assessing Authority, negate the premise that no response was filed. Proceeding with assessment without considering that request or affording an effective hearing breaches procedural fairness.

Statutory appellate remedy does not necessarily preclude writ scrutiny where an asserted breach of natural justice affects the assessment process. Faceless assessment procedures must comply with audi alteram partem: the taxpayer must receive reasonable time to answer a proposed adverse addition, and timely submitted replies and supporting material must be considered. Providing less than three working days and proceeding on an assumption of non-compliance despite acknowledged email submissions vitiates the assessment. Reconsideration must follow a reasonable hearing and consideration of the materials already furnished.

Determinate trust taxation under section 164 concerns measures intended to close tax-avoidance loopholes involving private trusts. The central legal issue is the validity of CBDT Circular No. 13/2014, which addresses the tax treatment of determinate private-trust arrangements under section 164 and the use of such structures for tax avoidance.

Supreme Court declined to interfere with the High Court's impugned ruling after considering the petitioner's submissions and record. The special leave petition was dismissed, and pending applications were disposed of. No underlying income-tax issue, statutory provision, or substantive legal principle is identified; the disposition rests solely on the absence of grounds for intervention.

Electricity subsidy computed as a percentage of energy charges incurred after production begins is a revenue receipt where it directly reduces manufacturing power costs. The purpose test governs characterisation: the scheme's object and operative mechanism prevail over the timing, source or form of payment. Although intended to promote industrial growth, the subsidy was limited to the post-production period and was neither linked to capital investment nor earmarked for asset acquisition, construction, capital-borrowing repayment or business expansion. It therefore provides operational assistance in carrying on business and is chargeable to tax as revenue income.
